IMPROVEMENT IN SHUTTER-FASTENINGS.

Specification forming part of Letters Patent No.

137,647, dated April 8, 1873; application filed November 20, 1872.

To all whom it may concern.-

Be it known that I, Miss ELLEN D. AN- DERSON, of Frederick, in thecounty of Frederick and State of Maryland, have invented aShutter-Fastener, of which the following is a specification:

The invention consists in combining a telescopic lock-bolt with twonotched brackets, arranged one near the inside, rear, and bottom end ofeach shutter, whereby the shutters may not only be securely lookedtogether or back against the house, but may be bowed or locked atvarious intermediate points, to afford a larger or smaller opening, anda greater or less degree of light and air.

Figure l is a perspective View of a pair of shutters attached to theirframe, and with my invention applied thereto. Fig. 2 is a modificationof the telescopic lock-bolt.

A in the drawing represents a shutter-frame, B B two shutters hingedthereto, and O the weather-strip, which also forms a stop for theshutters. D D are two brackets, each consisting of a horizontal plate,at, a lower perpendicular flange, d a perpendicular notched upperflange, (Z and a rod, (1 made fast to shutter at its upper end. E is thelock-bolt, formed of sliding bar F, sliding tube F and auxiliary tube FThe first two have each an eye,

through which passes one of the rods 0?, while the other itself slidesin tube F These parts are so connected that they form a telescopicjoint, and cannot come apart. H'H are two rods, connected by eyes h h,which might be substituted for bar and tubes without departing from theprinciple of my invention.

The operation is as follows: The shutters being closed against theweather-strip G, the lock-bolt at its shortest length is dropped into anend notch of each flange al and thus made to effectually prevent theshutters from being opened from the outside. lock the shutters back totheir utmost limit, they are turned thereto, and the lock-bolt, bein gdrawn to its greatest length, is inserted in the opposite end notches.If it is desired that the shutters be bowed orfastened with a greater orless opening, the lock-bolt is shortened accordingly, and dropped intointermediate notches.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A shutter-fastener, consisting of the two notched brackets D D, andtelescopic lockbolt E, constructed and applicable substantially asdescribed.
